These stations will use GPS to track the volcanos continued expansion, and their seismographs will allow scientists to triangulate the small earthquakes that take place within the volcano as magma moves around. Within the past 280 years a large explosive eruption produced pyroclastic flows that partially filled the Glacier Creek valley on the southwest flank. When operational,Cleveland volcano is monitored by only three seismic stations, which restricts AVO's ability to precisely locate earthquakes and detect precursory unrest that may lead to an explosive eruption. Partially because of their experience, Kluting and Turley have been following events more closely than most.

Turley said their first thought was that the bubbles were from something decomposing in the ponds or from tidal action, but theyd never seen them before and thought the bubbles remarkable enough to report them to Cameron, who is Tlingit and from Sitka. Low-frequency sounds typically travel greater distances than audible sounds because they lose energy at a lower rate. In this case, it would have taken the audible sound waves about seven hours after the explosion to be heard in Alaska, according to Fee.

Additional ash-producing events could occur again with little warning. Alaska Beacon maintains editorial independence. And in most of these cases, the disturbance quietens down after a few weeks or months, with no eruption. All of them occurred at with depths less than 6 miles (9 km) below sea level. If the gas bubbling through the lakes is magmatic, she said, itll be another sign of activity at the volcano. He said he was interested in learning more about whether other places also heard the booms, which may have propagated nonlinearly through the atmosphere. Hes also curious about whether there was something unique about Alaskas location at play. Turley said their first thought was that the bubbles were from something decomposing in the ponds or from tidal action, but theyd never seen them before and thought the bubbles remarkable enough to report them to Cameron, who is Tlingit and from Sitka. Risk isnt just the likelihood of an eruption, Coombs said. However, no noteworthy activity was observed in infrasound data. It can get going without much warning., He described the peak as an open system volcano, meaning its magmatic plumbing system is open and magmas can move to the surface really fast and it can start erupting almost with no warning., [Sign up for Alaska Public Medias daily newsletter to get our top stories delivered to your inbox.].
